CORN-SHOCKER.

SPECIFICATION formingpartof Letters Patent N 0. 723,623, dated March 24,1903. Application filed January 17, 1902. Serial No 90,133. (No model.)

To on whom it may concern.-

I Be it known that I, JOSEPH M. SHIVELY, of Alfred, in the county ofDouglas and State of Kansas, have invented certain new and usefulImprovements in Corn-Shockers, of which the following is a fulldescription, reference being had to the'accompanyingdrawings, in whichFigure l is a rear perspective view; Fig. 2, a plan view of the tableand springs, and Fig. 3 a detail of the locking device.

This invention relates to corn-harvesters of the type shown, described,and claimed in the patent granted to me, No. 559,7 54:,dated May 5,1896; and it consists in the construction hereinafter described andclaimed providing a stationary circularinclosure having a stalk-passageleading thereto, said inclosure located immediately above the rotatingshock-forming table and adapted to confine the butts of the stalks whilethe shock is being formed, and thus prevent them from spreading, and inother improvements which will be fully described and claimed.

In the drawings, Ais the main supportingwheel, andB the grain-sidesupporting-wheel.

The parts lettered C constitute the main frame, to which the wheels maybe considered to be attached. V

D is the rotary table, having the radial ribs d.

E is the shock-forming standard, having the radial arms 6. v

F representsthe walls of thecircular inclosure for confining the buttsof the stalks and preventing trash that may be left on the table fromescaping,and f the opening through which the stalks are brought to thetable after being severed by the cutting apparatus Upon the main frameis the rocking standard G, preferably made of square pipe, upon which Isecure the springsg, g, and g By the use of the set-screws g shown thevertical height of the springs may be regulated. Said rocking standardis located at one side of the stalk passage-way near the cuttingapparatus and is capable of being rocked. It is sustained by bearingssecured to the post G, reaching upward from the main frame.

I is a standard secured to the main frame, also capable of being rocked,upon which the springs 71 and t" are secured. The springs g, g, and gand the springs i and 'i are normally adapted to lie close to theshock-forming standard and be there locked, but, being resilient, toyield while the shock is being formed. The standard G is adapted to belocked from rotation in order to maintain the springs in that position;but it is set free by the locking device shown in Fig. 3. This lookingdevice consists of the single-tooth ratchet secured to the rockingstandard G, around which the springs g, g, and g are wound and secured.Reaching from the post G is the arm Z, in which the standard G ispivoted. To the end of this arm is the pawl Z, normally held inengagement by the spring Z When it is desired to set the springs free,the pawl is'disengaged. The springs 'i and i are held in position by asimilar locking device, but reversed, so as to operate oppositely, Thesprings g and i are fixed to the framework. It is not necessary to swingthem away,as it is those above them, for the reason that they are sonear the butts of the stalks that upon a little upward movement of theshock the said stalks are lifted above them.

The operation of the invention isas follows: The corn advanced upon isengaged by the cutting apparatus and directed rearward by the usualdevices, which may be of the kind shown in the above-mentioned patentgranted to me. The butts of the stalks move onto the rotary table, andthe tops are supported by the arms e. The rotation of the table carriesthe stalks thus received backward between the shock-forming standard Eand the springs g, g, g and g thus forcing the stalks toward a centralposition on the rotary table. In order that they may be maintained insuch positions,the springs 'i and that 7) upon the opposite side of theshock-forming standard engage them both at top and bottom, and the massis thusheld in'compact form until by its growth the shock is fullycompleted. At the time'the shockhas grown to nearly its full size thesprings cannot encircle the shock fully. It is at this interval that thewall F becomes particularly useful, for any straggling stalks that wouldotherwise escape from the edge of the table are held in position. Inorder that the fixed springs g and i may be secured outside of theinclosure and operate within, the slots f and f are made, and throughthem these springs pass. By having the inclosing wall stationary andproviding the opening F the stalks may be passed directly backwardwithout having to be forced over anything like a ledge, as would be thecase if the inclosing wall were on the rotary table itself. If on thesaid table it could not be of sulificient height to serve its purpose,for often a stalk will be held up somewhat by contact with other stalks.I lower the inclosure at the rear part of the machine, so as to avoidthe necessity as much as possible of raising the shock high whenswinging it to the rear, which would otherwise involve much more laborthan necessary on the part of the operator. In order that the operatormay pass from side to side of the machine to unlock the shaft G and thespring i, I provide the footboard C. This standard also enables him tostand on it when passing the twine around the completed shock. I curvethe rays d, as shown in Fig. 1. The springs g and i are necessarilycurved in the opposite direction. The result of this is that the slightresisting action of the springs, particularly 9 is such that the stalksbetween the latter and the said rays are more easily forced inward bythe spring than if the rays were straight.

The shock-lifting device will form the subject-matter of anotherapplication filed February 20, 1902. For the present purposes thelifting-crane of my patent above referred to may be considered asapplicable to the invention.

The gathering devices I use are not considered in this application, asthey form the subjectmatter of that above referred to. They serve onlythe purpose of bringing the stalks to the cutting apparatus, and as Iplace my cutting apparatus immediately in front of the rotating table Iproduce a machine much simpler than others, as by so doing the stalkswhen severed are permitted to fall directly into the space between thearms e and the series of springs opposing the said arms, as g, g, and gIt will be observed that the rotary table is so low that the butts ofthe stalks may be moved from the cutting apparatus directly to place onit. e represents arms secured to the lower end of the shock-formingpost, that lie flatly on the table While the shock is forming and aid inlifting the shock from the table. The springs g and t" force the buttsof the stalks inward, so these arms become in partsupports for the shockwhile being lifted.
